A handful of confirmed candidates reference files that are no longer in
the beets DB (removed by some other pass, or never re-imported after a
move) but are still sitting on disk -- beet remove can't match them by
id or path either way, so they failed forever. If the file still exists
after a "No matching items found" error, remove it directly instead of
counting it as a failure. Applies to both --apply and --apply-pairs.
